摘要：

At -78-degrees-C [W(= NPh)(CH2SiMe3)3Cl] reacts with 2-[(dimethylamino)methyl]phenyllithium in diethyl ether to produce a tetra-organotungsten(VI) complex which decomposes by an H(alpha)-elimination reaction generating a novel tungsten(VI) alkylidene with intramolecular coordination of an amine function; this complex reacts with norbornene to provide a cis-polymer that is the result of a selective ring-opening metathesis.
